The modelling and simulation of fracture networks is a critical component of the assessment of hot dry rock (HDR) geothermal resources and of the design and creation of enhanced geothermal systems (EGS). The production of geothermal energy from an EGS depends on fluid pathways through the HDR and thus connectivity of fractures is essential. One way of assessing and modelling fracture connectivi...

In Incremental Sheet Forming (ISF) strains can be obtained well above the Forming Limit Curve (FLC) that is applicable to common sheet forming operations like deep drawing and stretching. This paper presents an overview of mechanisms that have been suggested to explain the enhanced formability. The difference between fracture limit and necking limit in sheet metal forming is discussed. The neck...

Study about Fracture Mechanics and the root cause of fracture in order to estimates lifetime for Mechanical parts in designing process and manufacturing have tremendous role in this realm. Stress intensity factor comes into design which not only is dependent to geometry also extremely to load condition; for instance, it is important in failure processes (brittle and ductile Materials) or to pre...

– The relation between fracture surface morphology and the three-dimensional structure of crack fronts is investigated through direct observation of brittle cracks in gels. A key notion in this investigation is the discontinuity of the crack front, whose advancement creates the fracture surface. We discuss the significance of our findings in the studies of general three-dimensional brittle frac...
